      Description

      Occasionally users have run into weird "Unable to login" messages. Unfortunately, JAAS obscures the underlying exception message in many cases because it thinks leaking the exception might be insecure in itself. Enabling the "debug" option in the JAAS configuration gets it to dump the underlying issue and makes troubleshooting this kind of issue easier.
